Your maximum MP without benefit of items is a function of your experience level, your race, and whichever of your [[Spellcasting]], [[Evocations]], and [[Invocations]] skill is higher.

Version 0.14: This article may not be up to date for the latest stable release of Crawl.

Magic points or Mana points (usually abbreviated to MP) is the amount of magical energy which a given character has. It is used for spellcasting, for invoking divine powers (with the exception of Trog) and for evoking abilities granted by worn items, mutations, and intrinsic abilities.

Having your MP fall to zero is not directly lethal, but can be very hazardous for a spellcaster. MP will regenerate up to your maximum with time, and it is often recommended that spellcasters should rest up to full MP after every fight. There are also a few ways to restore MP more quickly:

Some items like rings of magical power or staves of power can increase a given person's reserves of magical power.

Your maximum MP without benefit of items is a function of your experience level, your race, and whichever of your Spellcasting, Evocations, and Invocations skill is higher. Training Spellcasting will get you more MP than Invocations, while Evocations is the least efficient for increasing your MP. Depending on your character, though, this may not be a concern.

A typical character starts with 1-6 MP (e.g. 1 for a Minotaur Fighter, 5 for Deep Elf Conjurer, 6 for Deep Elf Wizard) and eventually grows to many times that (30-40 for a level 20 Mummy Necromancer, or 50-60 when using extra items).

Formula

  • Unscaled MP = XL + Permanent MP + (XL*Species modifier + 1)/3 +

max(Spellcasting*XL*3/14 + Spellcasting, Invocations*XL/6.5 + Invocations/3, Evocations*XL/6)

  • Apply stepdown function

  • Permanent MP is 2 for a tutorial game, 0 otherwise.

MP modifiers

From Dungeon Crawl Stone Soup in-game documentation:

At Ba Co DE Dg Ds Dj Dr Fe Fo Gr Gh Gn Hu Ko Mf Mi MD Mu Na Op On Sp Te Tr Vp VS
0 0 0 2 2 0 N/A 0 1 0 0 0 0 0 0 0 -1 0 0 0 0 0 1 1 -1 0 1

History

Before 0.14, the formula was Unscaled MP = XL + Permanent MP + (XL*Species modifier + 1)/3 + max(Spellcasting*XL/4, Invocations*XL/6, Evocations*XL/6) where Permanent MP was a constant determined by the player's background and species.
